Adaptive dual-comb spectroscopy in the green region
Takuro Ideguchi, Antonin Poisson, Guy Guelachvili +2
Dual-comb spectroscopy is extended to the visible spectral range with a set-up based on two frequency-doubled femtosecond ytterbium-doped fiber lasers. The dense rovibronic spectru…
Raman-induced Kerr-effect dual-comb spectroscopy
Takuro Ideguchi, Birgitta Bernhardt, Guy Guelachvili +2
We report on the first demonstration of nonlinear dual-frequency-comb spectroscopy. In multi-heterodyne femtosecond Raman-induced Kerr-effect spectroscopy, the Raman gain resulting…
Mid-infrared frequency combs
Albert Schliesser, Nathalie Picqué, Theodor W. Hänsch
Laser frequency combs are coherent light sources that emit a broad spectrum consisting of discrete, evenly spaced narrow lines, each having an absolute frequency measurable within…
Adaptive real-time dual-comb spectroscopy
Takuro Ideguchi, Antonin Poisson, Guy Guelachvili +2
With the advent of laser frequency combs, coherent light sources that offer equally-spaced sharp lines over a broad spectral bandwidth have become available. One decade after revol…
